Clinical Causes: Atherosclerosis: Buildup of fatty deposits (plaque) inside coronary arteries reduces blood flow and can lead to blockage. Thrombosis: Formation of a blood clot at the site of a plaque rupture, obstructing blood flow. Coronary artery spasm: Sudden constriction of a coronary artery narrowing blood flow, potentially triggering a clot. Stress or physical exertion: Intense activity can sometimes precipitate plaque rupture or spasm. Other factors: Smoking, high blood pressure, high cholesterol levels, diabetes, and a family history of heart disease.

Key Symptoms: Sudden chest pain or discomfort, often described as pressure, squeezing, or fullness. Pain radiating to the jaw, neck, shoulders, arms, or back. Shortness of breath or difficulty breathing. Nausea, vomiting, or indigestion. Cold sweat or clammy skin. Lightheadedness or fainting.

Diagnosis Path: Electrocardiogram (ECG): Shows characteristic ST-segment elevation in the anterior leads indicating a STEMI. Blood tests: Elevated cardiac enzymes such as troponin indicate heart muscle damage. Coronary angiography: An imaging procedure to visualize the coronary arteries and identify blockages. Additional imaging may be used to assess extent of heart damage.

Treatment Protocols: Percutaneous coronary intervention (PCI): Often called angioplasty, this procedure involves inserting a balloon and stent to open blocked arteries. Thrombolytic therapy: Use of medications to dissolve blood clots when PCI isn't immediately available. Medications: Antiplatelet drugs, anticoagulants, pain relievers, beta-blockers, ACE inhibitors, and nitrates are used to manage symptoms and prevent further damage. Oxygen therapy: To ensure adequate oxygen supply to the heart tissue. Lifestyle modifications: Dietary changes, exercise, quitting smoking, and managing risk factors to prevent future heart attacks.
